Jiangsu Aokai New Materials, ọkachamara na-emepụta akwa akwa okpomọkụ PTFE, na-enye nyocha dị omimi. Matt sanding ọgwụgwọ na-eweta mgbanwe dị mkpa na n'elu Ọdịdị nke PTFE elu-okpomọkụ ákwà. Ọ na-agbanwe na mbụ ultra-inert, ultra-smooth surface ka ọ bụrụ ihe jikọrọ ọnụ, dị mfe wettable n'elu ọrụ site akụkụ atọ: anụ ahụ morphology, mkpuchi iguzosi ike n'ezi ihe na elu chemical ala.
1. Microscopic Morphology: Site n'elu ihu mirror dị nro ruo n'ike mmụọ nsọ
The untreated elu nke PTFE elu-okpomọkụ ákwà bụ dịtụ ire n'okpuru microscopes, kpụrụ a na-aga n'ihu ihe nkiri nke gbazee-sintered polytetrafluoroethylene. Ọgwụgwọ aja na-agbanwe nke ukwuu micro-morphology ya:
· Mmụba dị nkọ n'ịdị nkọ n'elu: Sanding maka igwe (abrasive belt, brush wires steel) ma ọ bụ mgbawa aja (corundum, alumina na-acha ọcha) na-egbutu ma na-emetụta elu ya, na-ese ọtụtụ obere oghere, olulu na elu. Ngosipụta isi ike isi Ra (mpụta mgbakọ na mwepụ nke profaịlụ enyochala) na Rz (ọnụego iri nke adịghị mma) na-amụba nke ukwuu.
· Formation nke n'ibu anchoring Ọdịdị: Ndị a Micro-grooves na-adịghị mfe scratches, ma 3D interlocking owuwu. Nke a bụ isi nke mmetụta mgbaka: adhesives na-abanye n'ime oghere ndị a ma gwọọ ya iji mepụta njikọ anụ ahụ maka njikọta ma ọ bụ mkpuchi na-esote.
· Ịdị n'otu agbanwe agbanwe: sanding kwesịrị ekwesị na-ebuga ọbụna matte imecha. Achịkwa usoro na-ezighi ezi na-ebute oke aja (mkpuchi mkpuchi siri ike) na patches na-adịghị mma, na-ebute ọdịdị ọdịdị dị iche iche na-adịghị mma.
2. mkpuchi iguzosi ike n'ezi ihe: Site na ihe nkiri na-aga n'ihu na-emebi emebi, mkpụrụ nke ekpughere
Nke a bụ ihe egwu kachasị dị egwu chọrọ njikwa usoro siri ike, na-ekpebi isi ọrụ nke ngwaahịa ahụ ozugbo:
· Thinning nke PTFE oyi akwa: Sanding bụ nnoo a anụ ahụ ihe mwepụ usoro. Ihe mkpuchi PTFE nke akwa na-ekpo ọkụ na-adịkarị site na iri ruo ọtụtụ narị microns. Nnukwu aja aja na-ebelata oke mkpuchi mkpuchi, na-eweda ike dielectric na ndụ ọrụ mgbochi corrosion kemịkalụ.
Ihe ize ndụ nke mkpụrụ osisi fiberglass ekpughere (nrụrụ aka kachasị njọ): Mgbe ịdị omimi na-egweri gafere ọkpụrụkpụ nke mkpuchi PTFE, a ga-ewepụ akwa fiberglass dị n'okpuru, na-ebute ọtụtụ ọdịda:
1. Ọnwụ nke ihe na-abụghị osisi: Fiber iko ekpughere na-arapara ngwa ngwa na ihe;
2. Mmiri na ntinye kemịkalụ: Mmiri mmiri na kemịkal na-abanye n'ime ákwà ahụ site na capillary edinam nke eriri iko, na-eduga na delamination na ngwa ngwa arụrụ ọrụ;
3. Ike arụrụ arụ mbelata: Mwepu nke eriri iko na-ebute mbelata dị nkọ na ike tensile nke akwa ahụ dum.
· Ọgbọ nke microcracks na akwakọba irighiri: Abrasive ọnwụ na PTFE na-ejikọta kenkuwa mgbaji na ductile tearing, eke microcracks na burrs tinyere uzo n'ọnụ na ala. Ka ọ dị ugbu a, ibe PTFE ndị a kpụrụ akpụ nwere ike itinyeghachi ya n'ụzọ na-adịghị mma n'elu, na-eme ihe arụrụ arụ dị ka agwaetiti nke na-emebi ntụkwasị obi nke mkpuchi ma ọ bụ njikọ na-esote.
3. Surface Chemical State: Site na Ultra-Inert na-arụ ọrụ
Ọ bụ ezie na sanding bụ isi ọgwụgwọ anụ ahụ, ọ na-ebutekwa mgbanwe na ihe ndị dị n'elu:
Ike elu elu : PTFE dị ọcha nwere ike elu ala dị ala (18-20 mN / m), na akụkụ kọntaktị mmiri n'elu 108 °. Mgbe aja ajachara, elu ndị e hiwere ọhụrụ na agbụ molekụla gbajiri agbaji na-ekpughere saịtị ndị na-arụ ọrụ ike ruo nwa oge, na-ebuli ike elu karịa 40 mN/m. Mmụba mmiri na-agbasa na mmiri n'elu, na-egosi hydrophilicity nwa oge, nke na-ada nwayọọ nwayọọ ka oge na-aga.
· Iwebata nwa oge nke otu ndị na-arụ ọrụ pola: Ike dị elu na-eme ka mmeghachi omume dị n'etiti ụdọ molekụla PTFE gbajiri agbaji na ikuku oxygen / mmiri dị na ikuku, na-emepụta otu ọrụ pola ozugbo dị ka carbonyl (C = O) na hydroxyl (-OH). Otu ndị a na-enyere njikọ kemịkalụ aka maka mgbanwe kemịkalụ ọzọ ma ọ bụ lamination nrapado.
Nchịkọta nke Mmetụta N'ozuzu
Na nkenke, ọgwụgwọ sanding tozuru oke na-emepụta ụdị uwe, nke siri ike, na-arụ ọrụ micro-nano na akwa PTFE na-emebighị mkpụrụ osisi fiberglass dị n'okpuru.
Ihe ndọghachi azụ ndị na - adịghị mma: na-achụ àjà mbụ arụghị arụ ọrụ, ịdị nro n'elu na nghọta, yana ihe egwu na-adịgide adịgide nke mmebi mkpụrụ na mkpirisi ndụ ọrụ.
Ya mere, isi nke usoro a dabeere na njikwa ziri ezi nke ihe mkpofu omimi - naanị n'elu PTFE oyi akwa abraded, na-enweghị emetụ na fiberglass mkwado ọkpụkpụ. A na-ezigakarị ákwà mkpuchi ahụ na mkpuchi ma ọ bụ usoro njikọ ozugbo iji nweta ohere zuru oke nke ọnọdụ elu ya na-arụ ọrụ nke ọma.
Anyị na-agbaso nkà ihe ọmụma ọrụ ọkachamara na iguzosi ike n'ezi ihe mgbe nile, na-eji obi anyị dum na-enye ngwọta ụlọ ọrụ nkwụsịtụ na ọrụ ndị ahịa na-eche echiche maka ndị mmekọ niile!
